To @ZZ whom t may concern:

Be it known. that I, ALVIN Q. WOLF, a citizen of the United States,residing at Dayton, in the county cf Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Sash- OperatingMechanism, of which the following is a specifi cation, reference. beinghad therein to the accompanying drawings.

This inventiony relates to improvements in sash operating mechanismdesigned especially for-use in hot or green houses, where a.

number of sashes are employed.

The several essential objects of the invention and the devices by whichthese objects are carried into practice are, first, a system of hangersand braces attachable to the ridgepole of the greenhouse-roof andadapted to su port and brace operating mechanism at eit er side of theridge-pole, according to whichever side of the building the sashes arelocated; second, a system of operating-gears and sprocket-wheels adaptedto be located in part at the end of the building and in part to besuspended from the ridge-pole and working in conjunction with a peculiarcable, one branch of which operates the sash-rods and is supported fromsagging, and, third, to numerous minor features of detail, allashereinafter more fully described and particularly pointed out in theclaims.

In the accompanying drawings, forming a part of this application, and onwhich like reference-letters indicate corresponding parts,

Figure l. is a side elevation of my operating mechanism, showing apartial interior view of a portion of a greenhouse with the apparatusapplied thereto. Fig. 2 is a detail enlarged perspective view of abracket used to suspend the cable-supporting rods; Fig. 3, a detailenlarged perspective view of a sashbar; Fig. 4', a detail enlargedperspective view of a sash-clip which may be used instead of the bar;Fig. 5,an enlarged side elevation of one of the sash-bars; Fig. 6, apartial elevation and sectional view, on a still larger scale, of one ofthese bars Fig. 7, an end elevation of the interior of a greenhouse,showing the operating devices for the cable also in elevation Fig. 8, anenlarged detail side view and partial sectional view of one of thesupporting or hanging devices for the cablesprocket; and Fig. 9, an endelevation of the same parts, showing more particularly their relation tothe ridge-pole of the roof.

i The letter A designates a portion of a'green I or post, but braced tothe ridge-pole. Thev hangers, specifically speaking, consist of a bar D,hung on a pivot-bolt E from a bracket F, bolted or otherwise secured tothe ridgepole, This bracket extends to one side of the ridge-pole in anangular direction, as seen more clearly in Fig. 9, so that by turningthe bracket end to it may be made to project from one side or the other,so as to suspend the hanging devices likewise to one side or the other.A brace G is connected by a bracket Il and bolts or screws to the bar Dand is also connected by a bracket I of similar construction to thebracket F and adapted to be connected to the ridge-pole and to extend toone side thereof, as in the case of the lbracket F. Theconnectionbetween the brace Gr and the bracket I is preferably pivotalby means of a bolt J. To the lower end of the bar D is secured a plateK, to which is pivoted a bearing-lever L, the supporting sprocket-wheelIVI being mounted eccentrically for a purpose hereinafter named on thislever at its lower end, while its other end is adjusted by a nut andbolt N, so as to take up the slack and create suflicient tension in theoperating-cable composed of sections of sprocket-chains O and P andintermediate sections of rods At suitable points along the greenhouseand to the frame thereofdsay to the under side of theridge-pole-brackets R are secured, having a number of holes S, intoeither of which a cable-brace T is hooked at its upper end, while itslower end engages one of several holes in a clip U, secured to the lowercable-rod Q. A second cable-brace V is engaged'with a staple or eye W,supported by one of the rafters, and also with one of the openings inthe clip U. The upper ends of these cable-braces T and V are somewhatseparated, while their lower ends are quite close together, and they areso situated that they will allow the cable to be adjusted in eith'erdirection, swinging on their pivots as the cable moves. Their purpose isto brace TOO IIO

the cable against swaying off to one side when the sash rods or liftersX are exerting a force in lifting or holding open the sashes to which atone end they are connected, while at the other they engage with one ofthe openings in the bracket U. The position of the sash lifters or rodsis at an angle to the rafters, so that when the lower end of the same ismoved by the cable the sashes will` be lifted or lowered according tothe direction of movement. The sashes are indicated at Y, and theconnection of the rods or lifters X therewith may be either through thesashbars Z, which are secured to the sides of the sash-frame and haveopenings a, in either of which an eyebolt b is secured for connectionwith such rods or lifters, or by means of a sash-clip c, designed to besecured to the llower bar of the sash-frame and having an opening, inwhich is secured the eyebolt b for the purpose stated. Either thissash-bar or sashclip may be used, according to the weight of the sash orthe particular situation. It will now be seen that the sashes arecontrolled by these rods or lifters X and that the cable is braced atthe points of attachment of the rods therewith, yet that the cable isfree to be adjusted longitudinally back and forth. This brings me to adescription of the mechanism employed to operate this cable. It consistsof a column or post cZ-say in the nature of a stout pipe-secured at itslower end to a post or part of the frame e by a clip f, and at its upperend secured to the ridge-pole by a short arm g, which may be turned onthe column d, so that the column may be set to either side of theridge-pole, while the arm extends over to the pole. This column carriesa stout bearing-plate h, clamped to the column by means of a clip i andbolts This bearinglate 7L carries a reversiblefork c, connected t eretoby bolts and nuts Z and bolted to' a brace m, which extends up and issecured to the ridge-pole. As seen from Fig. 7, this reversible fork 7cextends to one side of the column d, so that although the brace m isdirectly under the ridge-pole it connects with and braces the column andbearingplate which stand to one side of the ridgepole. This brace m andfork 71e, together with the hanger D G, constitute the hanger and bracedevices referred. to hereinbefore.

By reason of the construction which I have described the operatingmechanism may be laterallyv offset to either side of the vertical planeof the ridge-pole, and the cable may be corres ondingly offset so as tobring it more directfy under the sashes. This position of the cable isobviously advantageous, for the reason that excessive lateral thrust onthe cable is avoided and the connections between the cable and sashesmay be materially shortened, while the movements of said connections aremore nearly in the plane of movement imparted to the sashes.

' the other.

Referring now speciiically to the cable-operating mechanism, it willbeseen that in the bearing h there is mounted a shaft n, carrying asprocket-pinion o and a bevel-gearwheel p. On this sprocket-pinion ismounted the sprocket-'chain P, so that when the pinion is rotated in onedirection or the other the entire cable is moved in one direction or Thearts are so adjusted that the sashes will be lifted to their extremeopen position when the stop g on the lower branch of the cable comesinto contact with one of the teeth of the pinion o, and so that thesashes will be in their closed position when the stop r on the lowerbranch of the cable comes into contact with one of the teeth of thepinion 0. A bevel-pinion s meshes with and drives the bevelgear p, andas the pinion 0 is united to the bevel-gear p rotary motion is thusgiven said pinion. The bevel-pinion s is mounted upon an operating- Ishaft t, having a bearing at its upper end in a yoke u, suspended on theends of the shaft n. The lower end of the shaft t is mounted in a lowerbearing-plate i), held to the column d by means of a clip w and nuts andbolts This bearing-plate 'v also carries a fixed studshaft y, on whichis mounted a hand-wheel z, carrying a bevel -pinion z and a ratchetwheely. This bevel-pinion meshes with a crown-wheel t on the lower end of theshaft t. By these devices rotary motion is imparted to theoperating-shaft t, and thence to the other parts, as above indicated. Tolock the parts in any adjusted position, a pivoted detent fr is droppedinto the ratchet-wheel y. An arm w, carried by the stud-shaft y,supports the detent x.

Referring again to the detail character of the construction of thesash-rods X, attention is directed to Figs. 5 and 6, wherein this rod isshown in detail. It will be seen that it is divided into two parts, oneof which, X, is hollow to receive the other part, while any one of theseries of holes in the part X will receive a pin Y, the pin passingthrough a hole IOO IIO

in the other part of the rod, whereby the length of the entire rod maybe made greater or less to suit the particular situation where theapparatus may be mounted.

The mode of operation of my apparatus will now be undertsood, and I needonly therefore add that it is effective in use and safe and reliable inits control over and adjustment of the sashes, both with regard toholding them open or partly open and holding them closed. Thesprocket-wheel M being mounted eccentrically, as before stated, and asshown in Fig. 1, it will be seen that as the lower branch of the rod orcable moves to the left the wheel will revolve, bringing the shorter orminor radius thereof over to the right, thereby lengthening the cableand compensating for the arc described by sash-rods X as they swing tolift the sashes. As shown in Fig. 1, the sashes are partly up and thestop g and wheel M are in corresponding positions.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, isd
